After careful consideration, Johnson Controls has discontinued the GLAS Smart Thermostat (model number SIO2-10000). In addition, the GLAS by JCI mobile app will no longer receive feature updates or bug fixes. The GLAS Smart Thermostat will not be impacted by the discontinuation of app support, and will continue to function as it does today. Furthermore, Johnson Controls will continue to provide customer support for GLAS technical inquiries. Contact our customer support line at 1-833-297-GLAS for more information.

GLAS provides you with the information you need to help make your home healthier. The smart thermostat monitors relative humidity, total Volatile Organic Compounds (tVOCs), and equivalent CO2 (eCO2) levels indoors. It even reports pollen and air quality outdoors – especially helpful for asthma or allergy sufferers. And with features like fan runtime options, smart circulation, and smart ventilation, you’ll have more control over your air quality than ever before.
